I installed the Dart Piranha S3 flyscreen, because I couldn't hear any navigation instructions on my Cardo packtalk edge above 90 kph due to wind noise. This smart looking and well fabricated flyscreen takes away a lot of wind on my chest and the wind static around my helmet. It's not quiet but a lot less noisy. At low speeds I don't notice any difference. The materials used are very sturdy and snug. Easy to install with the included instructions. Love the looks!
It is worth mentioning that my bike has clip-ons installed, which makes my position quite low and forward compared to other Triumph Bobbers. Be aware for the 47mm diameter forks for newer models and the 41mm for older ones.
Delivery took a week to the Netherlands, but that was due to customs. Dart Ltd. sent it swiftly.
Superb service and their response to emails is very quick. Annette from Dart sorted out the issue with customs very professionally and promptly. I DO RECOMMEND!!!
